The increase in consumer demand for restorative and aesthetic dental treatment has resulted in a gradual upsurge of dental professionals relying on flowable composites (FCs) to meet consumer needs. All main manufacturers in the worldwide dental market offer flowable products together with the packable type. Scientific and technological improvements of FCs properties and handling characteristics have not only seen FCs grow in popularity but resulted in the development of different generations and types of dental FCs suitable for wide range of clinical applications. CPD/Clinical Relevance: It is useful for the dental practitioner to be aware of the classifications, composition and overview of FCs.

Flowable composite (FC) is a type of tooth-coloured restorative material with a lower viscosity compared to other types of resin composites. FC is considered as a versatile dental material, with a wide range of application. FCs have progressively gained importance in clinical dentistry. The increase in consumer demand has resulted in a gradual upsurge of dental professionals relying on composites in injectable form. Scientific and technological improvements in their properties and handling characteristics have not only seen FCs grow in popularity, but resulted in the development of different generations and types of dental FCs suitable for use in all cavity types, lining, core build-ups, and most recently, bulk-fill flowable composites. CPD/Clinical Relevance: To provide clinicians with an overview of the indications and clinical applications of the conventional FCs.

BACKGROUND: Two patients received ocular injuries from rusted metallic projectiles at their industrial workplaces. Said injuries resulted in the loss of their eyes by evisceration surgeries to prevent fatal infections. CASE DESCRIPTION: The first case, a man in his twenties, received a stock conformer immediately after surgery and started prosthetic therapy within 2 months. The second case, a man in his forties, started prosthetic therapy after 10 years. Definitive custom ocular prostheses were fabricated and relined according to conventional protocol. RESULTS: On issue of the prosthesis, there was adequate retention, aesthetics and stability to extra-ocular movements and treatment was considered successful for both cases. However, follow-ups showed noticeable prosthetic eye movements for case 1 which, to some extent mimicked the physiologic movement of its fellow natural eye. Case 1 adjusted to his prosthesis better while case 2 was still adjusting with little to no physiologic movement. CONCLUSION: Prosthetic rehabilitation should be started as early as possible to obtain optimum rehabilitative results.

Purpose: For making denture in maxillectomy cases is very difficult and challenging to get the retention tomake the denture stable in its position during functioning. This case report describes a clinical condition inwhich patient was treated with a maxillary obturator with zygomatic suspension wiring due to insufficientretention in the palate. Materials and Methods: A 63-year-old patient had gone to a subtotal maxillectomybecause following myofibroblastic sarcoma andwas issued with bilateral circum-zygomatic wiring hooksimmediately after surgery. The patient had less than a third of their alveolar ridge remaining and did notprovide sufficient retention on its own. The wires were used for the retention because natural retentioncould not get due to inadequate maxillary ridge. While the denture was being fabricated, a temporaryfeeding plate was provisioned to the patient. Counter hooks were implemented on the definitive upperdenture, posterior to molars, to attach to the zygomatic suspension hook. Final upper denture was furtherreinforced with denture adhesive on it. A lower denture was also fabricated for the said case followingconventional protocols of jaw relation determination. Results: The obturator provided with adequate sealand leak proof phonetics. The zygomatic wiring coupled with denture adhesive were sufficient to provideadequate retention. Conclusion: Zygomatic suspension wires coupled with counter hooked obturatorprosthesis provide rehabilitation of patients with palatal defects with inadequate maxillary arch forretention.However long-term repeated use of such wires might expose the patient to secondary infectionsand should be kept in consideration Clinical Significance: Circum-zygomatic suspension wiring providesufficient retention to sustain the upper obturator prosthesis in place. However, the retention was stillinadequate, so denture adhesives were used to make it more stable. Bangladesh Journal of Medical Science Vol.19(3) 2020 p.582-585
